Installing the projector

Choosing cables

If you are permanently installing the projector or using it with long cables, consider the
following suggestions when planning the installation:
Use high-quality cables. Use only video cables that are made with 75-ohm coaxial cable
•
and connectors. For high-resolution video, use low-loss video cables. For standard audio,
use audio cables that are shielded. For digital audio, use 75-ohm coaxial cables.
• Minimize cable length as much as possible. For video cables longer than 6 m (20 ft), use
low-loss coaxial cables. For standard audio cables longer than 6 m (20 ft), use 12-gauge
wire.
• Do not run audio or video cables next to power or network cables. If they must cross, cross
them at 90 degrees.
If you are installing cables in walls, use cables with necessary approvals, such as
•
Underwriters Laboratories (UL) approval.
• If you are running cables above a dropped ceiling, you must use plenum-rated cables if the
space above the ceiling is open to the space above other rooms. You must use plenum-
rated cables if you are running cables in a duct.
• Before installing cables permanently, check the setup with the final cables in the open.
